IPC: G01T3/00
Filed: 1961-10-27
Abstract: 947,104. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 17,1962 [Oct. 27,1961], No. 38479/61. Heading G6C. Neutron flux measuring apparatus comprises an irradiation unit of low neutron absorption displaced at a locality at which the flux is to be measured, a flowpath for a neutron activatable fluid through the unit between an inlet and an outlet, a monitor to measure the radio-activity of the fluid, and an outlet tube connecting the outlet to the monitors, the flowpath through the unit being such that the time taken for the fluid to pass through the unit is large relative to the time taken for the fluid to pass through the outlet tube so that the activity of the fluid measured by the monitor affords a measure of the of the neutron flux at the locality. In the drawing the irradiation unit 10 comprises a thin walled chamber of magnesium alloy provided with inlets 12 at one end, an outlet 13 at the other end and thin transverse porous partitions 17 in its interior. The outlet 13 and a reference outlet 19 are connected by fine bore capillary tubes housed in a braided cable 21 to counters 22, the outputs of which are compared in unit 23 and fed to a recorder 24. In operation a reduced pressure is maintained at the counters so that gas surrounding unit 10 is drawn through inlets 12 and reaches outlet 13 after about 50 seconds; the gas then takes about one second to travel from the outlet 13 to the counter 22. The gas may be argon or carbon dioxide and may be the reactor coolant. The unit 10 may be lowered into an empty fuel channel of a nuclear reactor by means of cable 21 and winch 29, and to scan the flux distribution along the channel the wind may be operated to cause the unit 10 to move up or down the channel at a constant speed, e.g. 0. 3 cm/sec., with continuous recording of the activity of the fluid passing through it. A plurality of units may be provided at various localities in the reactor core. The fluid passing through the irradiation unit need not be the reactor coolant or the gas surrounding the unit; a conduit may join outlet 19 to inlets 12 so that activatable fluid can be supplied through one of the capillary tubes in cable 21.

Title: Improvements in or relating to a method and apparatus for producing resilient sheet material such as floor or wall coverings
IPC: D06N7/00
Filed: 1956-12-18
Abstract: 823,432. Rolling granular material into sheets. ARMSTRONG CORK CO. Dec. 18, 1956 [Dec. 21, 1955], No. 38548/56. Class 87(2).  A method of producing sheet material, e.g. floor covering &c., from a "bank" of granular material disposed above the nip of a calender comprises supplying from the bank to the nip only sufficient material to form a compacted sheet in the tip and linearly oscillating the material immediately above the nip in a direction parallel to the axis of the calender rolls. The application of the method produces sheets having a polka-dot instead of an elongated "marbled" design. A calender 2 with rolls 3, 4, has a plate 5 with a hollow ground edge 6 in contact with the roll 4. The plate 5 is mounted on an L- shaped mount 12 guided by rollers 18, 19 and reciprocated by a motor 8 and a link 15. The position of the plate 5 keeps the granules from contacting the roll 4 until immediately prior to the nip and is adjustable vertically to vary the amount of material admitted to the nip. The edge 6 of the plate 5 may be serrated to allow local increases of material admitted to the nip thus producing localised marbling on the finished sheet.

Title: Improvements relating to signal generating apparatus for use in telephone and like exchange systems
Inventor: PRICE JOHN
IPC: H04M1/23
Filed: 1960-11-17
Abstract: 945,376. Subscriber's number sending equipment. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 8, 1961 [Nov. 17, 1960], No. 39534/60. Headings H4J and H4K. A key sender, employing multifrequency signalling and having its digit keys arranged in rows, comprises a number of frequency generating means operable by longitudinal displacement of respective actuating bars, the arrangement being such that actuation of a key operates directly an associated bar and also operates a further bar common to all the keys in a row, the latter bar in turn causing displacement of at least one further actuating bar. In the sender shown, three frequencies are transmitted for each digit, one of these frequencies is the same for all digits and serves as an identifying signal for stations on a party line, the other two frequencies being selected on a two-out-of-six basis. The keysender 1 (Fig. 1), may replace the dial in a conventional subset 2 and comprises a number of keys 4 pivoted at 5, a plurality of differently tuned reeds 10 and a magnet system 7, 8. Depression of a key causes the associated actuating bar 13a to 13h to be displaced to provide one element of the signalling code and also tends to rotate a further bar 18 (pivoted at 5) so that one or more other actuating bars, one of which provides the second element of the code, will be displaced by tongues 18<SP>1</SP>. Movement of bars 13 urges cams 12a to 12h out of engagement with reeds 10a to 10h (grain oriented silicon iron) so that the latter may vibrate. The resultant change in reluctance of the magnetic circuit causes a corresponding flux change in coil 9 with consequent transmission to line of an appropriate voice-frequency signal. Provision is made in the subset for signalling change of class of service signals whereby operation of key 23 (Fig. 1), causes the bar 18 associated with digit key " 0 " to be moved transversely so that a tongue 18<SP>1</SP>a is disengaged from actuating bar 13d while a tongue 18<SP>1</SP>b is moved into engagement with bar 13f. As an alternative to tuned reeds, the actuating bars may operate micro-switches associated with individual signal generators.
